Audiolabyrinth,
Those are Infinity RSIIb speakers, circa 1985. I've completely redone them with an external passive crossover featuring NorthCreek and Solen Heptalitz inductors and Mundorf and Duelund caps, new midrange diaphragms from Apogee Acoustics, rewired them with Cardas copper litz in teflon. They are excellent sounding, and not an easy load for an amp, but the above SET handles them beautifully.
